show performance remote_replication

show performance remote_replication

Function

The show performance remote_replication command is used to query the performance statistics on a remote replication task. Run this command to analyze the performance statistics on a remote replication task in real time.

Format

show performance remote_replication remote_replication_id=?

show performance remote_replication remote_replication_id_list=?

Parameters

Parameter

Description

Value

remote_replication_id=? ID of a remote replication task on which you want to query performance statistics.

To obtain the value, run "show remote_replication unified".

remote_replication_id_list=? ID list of remote replication tasks on which you want to query performance statistics.
  • To obtain the value, run "show remote_replication unified".
  • Separate the IDs of remote replication tasks with commas (,).

Level

Guest

Usage Guidelines

  • You will be prompted with optional performance statistics categories upon running this command. In this condition, typing a number or multiple numbers (separated by commas) for the selected categories and pressing "Enter" displays the performance statistics for those categories.
  • Performance statistics will be updated in real time.
  • Typing "q" on the command line interface (CLI) exits the active performance statistics display.
  • "remote_replication_id" is mutually exclusive with "remote_replication_id_list".
  • This CLI command can be used only on the primary array of an asynchronous remote replication task to query performance statistics.

Example

  • To query the bandwidth data for remote replication task "fcba35670003", run the following command.

    admin:/>show performance remote_replication remote_replication_id=fcba35670003 
    0.Bandwidth(MB/s) / Block Bandwidth(MB/s) 1.Time Since Last Synchronization (s) 2.Logical Bandwidth (MB/s) 3.Time Difference(s)  4.Synchronization Duration(s)
    Input item(s) number seperated by comma:0,1,2,3,4
    Bandwidth(MB/s) / Block Bandwidth(MB/s) :1
    Time Since Last Synchronization (s)     :0
    Logical Bandwidth (MB/s)                :16
    Time Difference                         :--
    Synchronization Duration                :--
  • To query the time difference between the data synchronization points in time of the primary and secondary resources for remote replication task "d8490b90ee140004", run the following command.

    admin:/>show performance remote_replication remote_replication_id=d8490b90ee140004
    0.Bandwidth(MB/s) / Block Bandwidth(MB/s)    1.Time Since Last Synchronization(s)         2.Logical Bandwidth(MB/s)                    3.Time Difference                            4.Synchronization Duration(s)                
    Input item(s) number seperated by comma:3
      Time Difference : 76129

System Response

The following table describes the parameter meanings.

Parameter

Meaning

Bandwidth.

Physical bandwidth consumed after link compression.

Time Since Last Synchronization.

Time after the last remote replication synchronization.

Logical Bandwidth

Logical bandwidth consumed without link compression.

Time Difference

Time difference between the data synchronization points in time of the primary and secondary resources in a synchronization period of asynchronous remote replication, expressed in seconds.

Synchronization Duration (s)

Synchronization duration (s).
